“Scripture presents contentment as a spiritual secret. It is one dimension of happiness, which is itself the fruit of a relationship. . . . Knowing the love of Christ is the one and only source from which true contentment ever flows. . . . The God whose fatherhood is perfect can be trusted absolutely to care for us on a day-to-day basis. So to realize that while planning is a duty and worry is a sin, because God is in charge, and to face all circumstances with an attitude of ‘praise God anyway’ is a second secret of the contended life” (J.I. Packer, Keeping the Ten Commandments, 103 & 104
